TREMOLO ATTACHMENT FQR CORNETS.

SPECIFICATION forming part of Letters Patent No. 282,448, dated July 31, 1883.

Application filed February 24, 1883.

To all whom it may concern Be it known that I, WILLIAM S. DITTER- LINE, of Mauch Chunk, in the county of Carbon and State of Pennsylvania, have invented a new and Improved Tremolo Attachment for Oornets and other like Wind-Instruments, of which the following is a full, clear, and exact description.

V The object of my invention is to provide a new and improved attachment for cornets and other like musicalinstruments operated by the mouth, whereby the tone produced is made vibratory.

The invention consists of a tube adapted to constitue the echo-tube of the eornet, or a mutetube to be applied to the bell of the instrument, said tube having a valve or disk con nected thereto by a spring or lever, and arranged to vibrate on the outer end of said tube, essentially as hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal elevation of a cornet provided with my improved tremolo, showing it applied on the echo-tube. Fig. 2 is a longitudinal elevation of amute-tube provided with my tremolo, the mute-tube being held in the bell of the instrument. Figs. 3 and 4 show modifications of my improved tremolo attachment.

A disk, A, covered with leather, rubber, or other suitable material on one side, is attached to one end of a lever, B, pivoted to the echo tube 0 of a cornet in such a manner that the weight of the lever B holds the covered side of the disk against the opening of the downwardlybent end of the said tube. The wind issuing from the end of the said tube swings the disk a short distance from the end of the tube, the weight of the lever throws it back again, and so on, whereby the tone will be vibrated or (No model.)

made tremulous. The same device can also be attached to the end of a mute-tube, D, which is inserted in the bell of the instrument, as shown, so that the wind that would otherwise issue from the bell must pass through the tube D. If desired, the lever B can be provided with an adjustable weight, E, which can be adjusted a greater or less distance from the end of the lever, whereby the disk A' will be pressed against the end of the tube with greater or less 5 pressure. The end of the tube can also be made straight, as shown in Fig. 3. In place of the lever B a spring, F, may be used to press the disk against the end of the tube. The disk can be attached to a cross-piece slid- 6o ing in longitudinally-slotted guides, and held against the end of the tube by a spring. The disk must be covered, so as to fit closely against the end of the tube.

By means of my tremolo attachment a very good effect can be produced in different kinds of music-such as sacred music, dirges, and all other music of aslow and mild nature.

The disk can be made of metal, rubber, bone, ivory, wood, 85c.

The attachment is very inexpensive, and can be attached to all cornets or like wind-instruments.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent The tube adapted to be held in the bell of the instrument, and to also serve as the echotube, and having a valve or disk connected thereto, adapted to be operated by the pnlsa 8o tions of the wind escaping from the tube, essentially as shown and described, and for the purpose set forth.

WILLIAM S. DITTERLINE.
